Rocky Flats Nuclear Weapon Plant Disaster near Denver, Colorado. It produced plutonium triggers resulting in significant radioactive contamination.

The Rocky Flats Plant was a U.S. Department of Energy nuclear weapons facility located near Golden, Colorado, operated from 1951 to 1992. It produced plutonium triggers ("pits") for nuclear weapons, resulting in significant radioactive contamination, a 1989 federal raid, and subsequent closure. The site was largely cleaned up, designated a Superfund site, and is currently the Rocky Flats National Wildlife Refuge, though long-term health risks are still debated.

Plutonium pit production was halted in 1989 after EPA and FBI agents raided the facility[5] and the plant was formally shut down in 1992. Rockwell then accepted a plea agreement for criminal violations of environmental law.[6] At the time, the fine was one of the largest penalties ever in an environmental law case.[7]

If you visit the Rocky Flats National Wildlife Refuge northwest of Denver, you see different types of wildlife, miles of hiking and biking trails and acres of rolling prairie.

But you don’t see any trace of the astonishing history of what happened there during the Cold War: The Rocky Flats plant made plutonium triggers for nuclear weapons until it was shuttered in the early 1990s.

The buildings used in processing the plutonium were destroyed and the area was cleaned up under a Superfund site designation. And after a series of sometimes contentious public hearings, the wildlife refuge opened to the public in September 2018.

Filmmaker Jeff Gipe explores that history in a new documentary, Half-Life of Memory: America’s Forgotten Atomic Bomb Factory. Gipe grew up in nearby Arvada. His father worked at the plant in the 1980s.

Gipe says he made the film to remind people of the hazards buried beneath the wide-open spaces of the wildlife refuge, and to share the voices of workers whose lives were affected by the dangerous materials processed at Rocky Flats.

We at the Union of Concerned Scientists (UCS) are very excited to invite you to a special virtual screening of the acclaimed documentary, Half-Life of Memory, to be followed by a live discussion with the film maker, Jeff Gipe. The film exposes the impacts of nuclear weapons production on individuals and communities.

There are people that say that Albert Einstein was a genius... However... His ideas led to the Atom Bomb... The worst invention in the entire history of the world... And his ideas also led to the Atomic Power Plant... The second worst invention in the entire history of the world... It's entirely possible that we should have Fewer Geniuses if  --->THAT<--- was what their ideas help create...
